^Yea I was gonna say the same thing, there's probably not a very big chance of them catching ayu's name, but just to be on the safe side it may be best to only include "AHS" and not her name. Should someone miss this and still include "ayumi hamasaki" and be the winner, we can still have it modified. I doubt someone can integrate something as long as "ayumi hamasaki sekai' into a well working logo.
